Chemical Structure

2'-Methoxy-[1,1'-biphenyl]-4-thiol CAS 1443340-89-3 chemical structure

Description

CATO supplies 2'-Methoxy-[1,1'-biphenyl]-4-thiol (CAS 1443340-89-3), a certified reference material (molecular formula C13H12OS, MW 216.30 g/mol) for analytical method development and quality control.

2'-Methoxy-[1,1'-biphenyl]-4-thiol (C13H12OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
